It's awhole lot easier than that you just need a scanner. If thers a fault for your cam senors, ther the problem, if your mass air flow is at fault you will also have fuel trim faults same as a clogged fuel filter. if you have a single cylinder misfire, swap the plug to another cylinder and swap the coil to a seperate cylinder i.e. misfire cylinder 3 swap the plug with the one from cylinder 1 and the coil with cyl 2. if the fault follows one of them thers ur problem if it stays its your inkector. if you have mutiple misfire and lean faults stored most likely you need and fuel filter or its your crankcase vent valve. Mass air flow sensors rarely set misfire faults they will set fuel trim faults and also may set a fault for the icv
